d3-sankeySeq

d3-sankeySeq.js is an adaptation of the sankey plugin for sequential data. Unlike the standard sankey diagram, where the position of the nodes are determined by an iterative procedure, sankeySeq is suitable for sequential data for a given sequence (e.g. time sequence) where the node positions are fixed.

Here is an example how to use it.

Installing

If you use NPM, npm install d3-sankeyseq.

API Reference

<script>
var sankeySeq = d3.sankeySeq();
</script> 

function	parameter	explanation
debugOn()	boolean	e.g. sankeySeq.debug(true) turns on/off the console.log debugging. The default setting is false.
size()	2-dim array	, e.g. sankeySeq.size([600, 400]) sets size of the SVG based on an array [width, height]. The default size is [700, 500].
margin()	integer	e.g. sankeySeq.margin(10) sets margin in pixels for top, right, bottom, left. The default margin is 0 px.
sequence()	array	e.g. sankeySeq.sequence(["2000", "2001", "2002"]) sets the order of the sequence based on an array. The default order is ascending.
categories()	array	e.g. sankeySeq.categories(["A", "B", "C"]) sets the order of the categories based on an array. The default order is ascending.
sequenceName()	string	e.g. sankeySeq.sequenceName("year") sets the name of the x axis. The default name is "sequence".
categoryName()	string	e.g. sankeySeq.categoryName("state") sets the name of the y axis. The default name is "category".
valueName()	string	e.g. sankeySeq.valueName("frequency") sets the name of the value. The default name is "value".
nodeWidth()	integer	e.g. sankeySeq.nodeWidth(20) sets the width of a node in pixels. The default width is 15.
nodePadding()	integer	e.g. sankeySeq.nodePadding(10) sets the y-padding between the categories in pixels. The default padding is 8.
nodes()	array	e.g. sankeySeq.nodes([{"node":0,"name":"node0"},{"node":1,"name":"node1"}]) sets the list of nodes to the specified function or array. The default is [].
links()	array	e.g. sankeySeq.links([{"source":0,"target":2,"value":2},{"source":1,"target":2,"value":2}]) sets the list of links to the specified function or array. The default is [].
maxValue()	integer	e.g. sankeySeq.maxValue(100) sets the reference nodeHeight in pixels for computing the vertical scaling factor. The default is the node height of the node with the largest value.
